6 W ATTORNEY Patented Oct. 2, 1934 UNITED STATES PATENT OFFICE ENDLESS TAPE STOCK QUOTATION PROJECTING MACHINE Application November 3, 1930, Serial No. 493,035 Renewed October 28, 1933 17 Claims. (Cl. 178-42) This invention relates to endless tape stock quotation projecting machines.

Among the objects of the present invention, it is aimed to provide an improved endless tape stock quotation projecting machine in which the tape is continuously operated during the reporting period, whether the ticker is operating or not.

Another object of the present invention is to provide an improved endless tape quotation projecting machine in which there is an ink removing means, such as a soapy solution or the like, including a rinsing solution'for removing the ink removing solution after the ink has been removed.

With the endless tape quotation projectors heretofore known in which the tape stops with the ticker, and the period of rest of the ticker is indefinite, considerable difiiculty has been encountered as a result of the different treatments to which the various portions of the endless strip of tape are subjected, resulting inldifierent degrees of tension, diiferent degrees of ink retaining qualities, different degrees of ink receiving qualities and the like.

As an instance, with an endless tape consisting of a paper composition, when an ink removing solution such as tetrachloride or the like, is used and a'heating chamber isused for drying the tape during aperiod of rest, the portion of the tape located in the cleaning solution will soak and become thoroughly impregnated with the cleaning solution and on the other hand'the next succeeding area located in the heating chamber may be so dried as'to dry out certain of its inherent components. Consequently, when the tape is, after such a period of rest, started on its way through the printer, suflicient time will not ensue to permit "the soaked portion of the tape to be dried to anydegree approaching the degree of dryness of the aforementioned dried portion and consequently when the successive areas pass through the printing machine, different degrees of ink receiving surfaces will be presented to the printer with resulting different impressions so that when these successive portions then appear in the projecting machine and are magnified from ten to twenty times, the different impressions 'will be apparent to the eye and produce an objectionable picture of different shades and qualities of images. Furthermore, the different tension of the succeeding portions of tape will cooperate differently with the tape advancing means to produce different rates of feed and the consequent irregularities.

To the latter end, the present invention aims cessive ink impressions will be uniform and con- 6 sequently also the successive images, and whereby the ieed of the successive portions of the tape through the projecting machine will be uniform.

The present invention also aims to provide an improved endless tape projecting machine in which excessive heating and excessive soaking of the tape will be prevented, thus to cater to the longevity of the tape. To this end, the present invention aims to provide an endless tape projecting machine inwhich the tape is continuously fed through the printer and projecting machine without interruption so that no one portion of the tape can be subjected to a greater period of ink removing treatment or drying treatment than another.

It is still another object of the present inventionto provide an improved endless tape pro-- jecting machine inwhich a compact extended drying bath is provided for the tape after pass ing through the ink removing bath, rinsing bath and the like, whereby the proper drying of the tape will be insured before the tape is returned to the printer for receiving a new impression and to'the succeeding'projecting area.

It is still another object of the present invention to provide an improved endless tape-projecting machine in which a comparatively cheap and inexpensive ink removing'bath can be used whichcan be attended by the average unskilled mechanic attending upon this type of machine in the average brokerage house. To this end, the present invention aims to provide an endless tape stock quotation projecting machine using an ink which can be readily removed or washed off the average tape bymeans of a soapy solution such as a soap bath and a rinsing bath provided for removing the soapy solution from the tape after being subjected to the cleaning treatment and a drying chamber provided for drying the tape after passing through such successive baths.

Furthermore, with the ordinary tickers today in use, knurled feeding rolls are used to grip the tape after each printing action to advance I and cut into the tape, leaving a cut track in the tape. If such tape were repeatedly fed through the ticker as is the case with the endless tape, the cuts and tears from the feeding rolls would soon irreparably cut the tape. To this end, the present invention also aims to provide an endless tape projecting machine in which the tape feeding action is continuous so that such knurled feeding rolls may be dispensed with and instead thereof smooth faced feeding rolls used which will satisfactorily feed the tape through the machine in a. continuous motion without any danger of cutting or tearing the same.

Heretofore, it has also been found that the ordinary tape today in use composed of cellophane paper and the like is hygroscopic and thus not' only sensitive to changes in humidity with consequent objectionable effect on the feeding action of the stock quotation projecting machine but also objectionable for use in an endless tape projecting machine where the tape is repeatedly immersed in an ink removing bath or the like since great difficulty would be encountered in properly drying the tape before returning the ink removed portion to the ticker. Tape composed of cellulose acetate, a slow burning film stock, practically hydrofuge in character would be practicallyimmune to changes in humidity but due to the cost thereof would be impractical, if the tape were not intended for repeat use. To this end, the present invention aims to provide a stock quotation projecting machine including an endless tape composed of such cellulose acetate or the like hydro-- fuge substance which on account of the short length of the tape so used would not be objectionable from the standpoint of cost and due to its hydrofuge character would be quickly freed from from the liquid of the ink removing bath after passing through such bath or the like.

It is still another object of the present invention to provide an improved endless tape stock quotation projecting machine including a ticker for transmitting records of stock quotations on an endless tape, a projecting device, a device for eliminating such records after projection and a tape puller for continuously feeding the tape through said ticker and projecting device without interruption whether said quotations are transmitted or not during the quotation reporting period.

These and other features, capabilities and advantages of the invention will appear from the subjoined detail description of one specific embodiment thereof illustrated in the accompanying drawing in which Figure 1 is a front elevation of a stock quotation projecting machine made according to the present invention; and

Fig. 2 is a section on the line 2-2 of Fig. 1.

In the present embodiment, there is provided a platform 1 on which is mounted a ticker stand 2 for a ticker 3 of the high speed ticker type today extensively in use. This high speed ticker is provided with a supply reel 4 (not used) and feed rollers 5 and 6.

Adjacent to the ticker stand 2, there is pro-,

vided the lamp housing 7 having an extension 8 provided with a light aperture 9 across which the tape passes to the tape pulling roller 10 of the tape pulling mechanism supported in the housing I1, which housing 11 is also supported on the platform 1.

When the tape T preferably composed of a cellulose acetate composition, a slow burning fllm stock, which in the present instance is an endless strip, passes from the rollers 5 and 6 of the printer 3, it will first pass underneath the type wheel '12 of the printer and then under the finger 13 which is pivotally mounted on the extension 8 and engages the tape T between the ticker and the rollers 14 and 15 at the entrance end of the light aperture 9. The finger 13 serves to cooperate with the rollers 14 and 15 to dissipate or absorb any vibrations transmitted to the tape T by the ticker 3. From the rollers 14, and 15, the tape T passes over the light aperture 9 extending the full length of the extension 8 to the rollers 16 and 1'7 at the exit end of the light aperture9 from which the tape passes to the smooth faced tape pulling roller 10 mounted on the shaft of the worm wheel 18 in mesh with the worm 19 mounted on the shaft 20 journaled in the housing 11.

The shaft 20 is provided with a sheave 21 which is connected by the belt 22 with the sheave 23' on the shaft of the motor 24 also mounted on the platform 1.

The tape T is maintained in engagement with the tape pulling roller 10 by the smooth faced pressure roller 25 mounted on the bracket 25 pivoted at 26 and provided with a weight for frictionally pressing the tape into engagement with the tape pulling roller 10. From the tape pulling roller 10, the tape T preferably passes to and over the idler 27, preferably disposed directly above the platform 1 and serving as a guide for the tape in its passage to the opening 28 formed in the platform 1 before passing through the same into the ink removing bath 29.

The optical system here used is well known with machines of this type and would consist essentially of a lamp 30 in the lamp housing provided with a reflector 31 from which the light of the lamp 30 is directed to and through the condensers 32 and 33 from which the light is directed onto T the deflector or mirror 34 at the bottom of the extension 8. The light is directed upwardly by the mirror 34 to and through the condenser 35 and from there directed up through the tape to the objective lens located in the objective lens holder 36 supported at the end of the bracket 37 mounted on the top of the extension 8. From the objective lens the light passes up to the screen housing first striking the mirror or deflector 38 and being directed by it to the deflector or mirror 1 39 and from the mirror 39 to the screen 40.

As the tape T passes below the platform 1, it passes through the ink removing bath 29 already referred to, then through a rinsing bath and then through a drying chamber up through the opening 41 on the platform 1 to the idler 42 supported adjacent to the high speed ticker 3 through which the tape T then passes.

Preferably secured to the platform 1 as indicated, and suspended therefrom there is provided the housing member H having vertical and end side walls extending from the platform 1 down to the bottom 43 thereof.

The housing H is divided into three chambers by the partitions 44 and 45 extending up from the bottom 43. The partition 45 forms with the end wall 46 the ink removing chamber 4'7. The space formed between the partitions 44 and 45 is used to constitute the rinsing chamber 48 in the present instance, and the space formed a between the partition 44 and the end wall 49 constitutes the drying chamber 50.

In the ink removing chamber 47 in the present instance, there is provided a roller 51 under which the tape passes on its way through the .lower portion of the chamber 47 to the roller 52 and then up under the roller 52 to the large roller 53 preferably disposed above the partition 45 to'clear the same. The tape T passes over the roller 53 and down on the other side of the partition 45 into the chamber 48 to pass under the roller 54 and from the roller 54 under the roller 55 whereupon the tape passes up over the roller 56 disposed above the partition 44 to clear the same. From the roller 56 the tape then passes down and through the drying chamber 50 passing over a number of rollers arranged to form an extended compact path to be traversed by the tape before leaving the drying chamber in order to effectively dry the tape. As an instance, the present drying chamber is provided with nine rollers disposed in two rows, the four rollers 5'7, 58, 59 and 60 at the upper end of the drying chamber and the row of rollers 61, 62, 63, 64 and 65 at the lower end of the drying chamber. The tape passes to and fro across theserollers'as indicated in Fig. 1 before passing out throughthe opening 41. As an instance, the tape T passes under the roller 61, then up over the roller 57, then below the roller 62, then above the roller 58, then below the roller 63, then above the roller 59,- then below the roller 64, then up over the roller 60 then finally under the roller 65 and up through the opening 41.

The roller, 65 in the present instance is supported in the slot 66 formed in the support 67 whereby the same maybe vertically movable and thus act as a take-up to take up the slack in the tape T before it passes to the ticker 8.

In the present instance as indicated in Fig. 1, they chamber 4'7 is provided with a liquid solution or bath 29 composed-of a suitable ink removing liquid. Preferably this liquid is composed of water and a suitable soap element such as soap powder, soap flakes and the like, formed into a soapy solution. The chamber 48, in the present instance, is provided with a rinsing solution 68 which may be ordinary water. The drying chamber 50 is preferably circulated with a drying medium such for instance as hot air or the like which is introduced into the drying chamber 50 through the inlet 69. r

Preferably the ink removing chamber 4'7 is also provided with a pair of squeegee rollers '70 and '71 between which the tape is impinged after it has left the bath 29 and before it passes to the roller 53. These squeegee rollers '70 and '71 serve to squeeze the tape after it leaves the ink removing bath, squeezing the ink removing solution from the surface of the same, similar to the conduct of a washing machine wringer.

The rinsing chamber 48 is also provided with a pair of squeegee rollers '72 and '73 between which the tape is impinged after it leaves the rinsing bath 48 and before it-passes over the roller 56. These squeegee rollers: '72 and '73 also serve to squeeze the tape'T as it leaves the chamber 48 to squeeze off the liquid accumulated thereon.

To aid the tape pulling roller 10 in feeding the tape T through the machine, and on the other hand to distribute the pulling strain on the tape,

' normal printing operation at the rate of about there is provided an auxiliary pulling roller '74 at the. lower entrance end of theink removing chamber 4'7 and another auxiliary pulling roller near the outlet end of the drying chamber. The tape pulling rollers '74 and '75 are drivingly connected. The idler 51 is disposed to frictionally press the tape T into engagement with the roller '74 and impart a feeding or advancing movement to the tape. Idler 60 on the other hand is acter.

disposed to frictionally press the tape T into engagement with the roller '75 which is drivingly connected to impart a feeding or advancing movement to the tape. The squeegee rollers '71 and '73 are similarly drivingly connected so that they will not retard the feeding movement of the tape while squeezing the same and on the other hand actually help to advance the same.

The driving connections for the rollers '74 and '75 and the squeegee rollers '71 and '73 will now be described. The shaft of the squeegee roller '71 is provided with a sheave 76 which is connected by the belt '77 with the sheave '78 on the shaft of the worm wheel 18. The shaft of the squeegee roller '71 is also provided with a sheave '79 which is connected by the belt 80 with the sheave 81 on the shaft of the tape pulling roller '74. The shaft of the squeegee roller '71 is also provided with another sheave (not shown) which is connected tothe sheave 82 of the squeegee roller '73 by the belt 83. The shaft of the squeegee roller '73 is also provided with another sheave which is connected to the sheave 84 of the tape pulling roller '75 by the belt 85.

The roller '74 in the present instance is composed of a suitable felt or the like to act as a 'bufiing roller, in addition to cooperating with the tape pulling roller 10' to advance the tape. This bufling roller '74 as indicated by the respective dimensions of the sheaves '76, '79 and 81 'is preferably driven at a faster speed than the tape pulling roller 10 and the squeegee rollers '71 and '73. Of course, this bufling roller or wheel '74, slippingly engages the tape so as to effectively pursue its buffing action without interfering with the uniform feeding of the tape. a

, In the operation of this machine, the tape feeding rollers 5 and 6 of the ticker 3 are opened so that the only feeding movement imparted to the tape T will be that imparted thereto by the continuously operating tape roller 10, bufling wheel 74, squeegee rollers '71 and '73 and the tape pulling roller '75. This continuous movement of the tape T through the ticker 3is possible and practical with a high speed ticker of the type today extensively in use producing five hundred characters or more per minute. This arrangement however is entirely practical when the printer operates at not more than three hundred characters per minute. While the high speed tickers of the type today extensively used will not print in excess of nine hundred characters per minute, the present arrangement would be entirely practical with high speed tickers whichexceeded'in speed nine hundred characters per minute.

With the high speed tickers today in use, printing approximately five hundred characters per minute, each cycle of operation for printing a character consists in selecting the type, printing on the tape and feeding the tape. action is apparently the shortest so that the printing-operation consumes about .0005 minute per character or approximately .03 second per char- It is also known by actual test that with the high speed ticker of the type today extensively used the tape is discharged from the same during 62 inches per minute. In checking back, we find that since the distance from .center to center of successive characters is. about one-eighth of an inch on the tape so that 8'characters can appear within an inch, when we multiply 8 by 62 we obtain the figure 496, a figure very closely approximating 500, the approximate number of characters per minute printed by the high speed The printing tickers when under normal operation. From this calculation, we find that the tape discharged per second would be about 1.03 inches from which it would appear that during the time that a character is printed, to wit .03 second, an infinitesimal part of tape would be moving, to wit only .03 inch. It would thus be apparent that, if at all, the tape would slip but slightly, at most to wit .03 inch relative to the type during this period, and this distance of slippage would be so small that it would be invisible to the eye. With regard to the time .03 second allotted to the printing part of the cy cle in this calculation, consideration should be given to the fact that this includes the time required for the printing hammer to approach the tape and recede therefrom, in addition to the period of contact. From this, it would thus appear that the moment of contact of the tape between the type wheel and printing hammer is considerably less than .03 second, since this is the only moment when any resistance is offered to the free passage of the tape, and it is thus apparent that the amount of slippage occurring, if any, is so slight as to be incalculable. However, when it is considered that the elasticity in paper tape or cellophane is fairly high, the yield would easily compensate for this slight retarding action imparted to the tape during the printing movement and consequently still less slippage would. take type wheel is moved by the printing hammer less place between the tape and the type. Consideration also should be taken of the fact that the type today used on the high speed tickers is composed of a yieldable substance, such as rubber and consequently the slipping tendency of the tape would also be taken up by this rubber type.

From the foregoing, it would thus appear that due to the yi'eldability of the tape, to wit paper, cellophane or the like and .possibly also the yieldability of the rubber type, when the momentary contact is considered, to wit the movement of less than .03 inch of tape in less than .03 second, that so far as the eye is concerned, the vibration transmitted to the tape would be invisible. It would thus appear that the vibration transmitted to the tape would result in longitudinal vibrations that would be absorbed by the tape pulling roller as quickly as formed. This will be particularly apparent when consideration is taken of the length of tape which is subjected to the pulling tension of the roller 10 which pulling tension extends from the type wheel 12 through the printer and projecting machine, to wit a length of about 10 inches more or less. There is no tendency to transmit lateral waves to the tape since the tape at the point of contact with the "than .0156 inch, the hammer in the high speed ticker'mbving less than .03 inch in all and of course consuming about one-half that distance,

. to wit .0156 inch in approaching the tape.

From the foregoing, it would thus appear that after the tape pulling roller 10, buffing roller 74, squeegee rollers 7'1 and 73 and tape pulling roller 75 are timed to feed the tape at approximately 62 inches per minute or slightly in excess of that speed with a, ticker printing at the rate of 500 characters per minute, there will be no danger of the printing impressions being blurred due to the movement of the tape; and on the other hand. dueto the continuous movement of the tape T,

any two given portions of the tape no matter how remotely removed from one another will always appear at the printing point in about the same condition as to moisture content and tension and 1 similarly at the light aperture. In other words,

will be effectively ironed out by the finger 13,

rollers 14, 15 and rollers 16, 1'7 so that the portion of the tape appearing at the light aperture 9 will be smooth and even at all times.

The finger 13 co-operates in a rather unique manner with the feeding action to prevent the slippage of the tape relative to the type wheel when contact is made between the type wheel and printing hammer. During this momentary lag if any, the finger 13 will yield so that the ,loop formed by the finger 13 will be taken up momentarily to compensate for the resistanceoffered by the momentary contact of the tape between the type wheel and printing hammer. As

a result of the movement of this finger 13 the velocity of the tape across the light aperture will remain constant.

From the foregoing, it will also appear that since the feeding rollers 5, 6 which are generally knurled rollers are kept opened, the serrations ordinarily imparted to the tape by such rollers will not be so imparted, and since the tape feeding roller 10, pressure roller 25 and all the other rollers contacting with the tape are smooth faced rollers, the tape will be spared from such serrations and the life of the tape consequently indefinitelyl extended.

From the'foregoin'g, it will also appear that since the tape here used is preferably composed of a cellulose acetate base, that is a slow burning film stock, which is comparatively hydrofuge in character, the difficulties heretofore encountered as the result of humidity changes will now be overcome. Similarly since successive areas of the tape are here successively immersed in an ink removing bath and the like, the hydrofuge character of the tape will be of material aid in quickly freeing the tape from? the liquid solu tion so that it may be effectively dried in the drying chamber before being returned to the printer .3 and projecting machine.

From the foregoing, it will also appear that cations may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claims. a
